5 Safety requirements and/or measures The machine shall comply with the safety requirements and/or protective measures of this clause. In addition, the machine shall be designed according to the principles of clauses 5 and 6 of !EN ISO 12100-1:2003" for hazards relevant but not significant, which are not dealt with by this document (e.g. sharp edges). For guidance in connection with risk reduction by design, see !4.1 of EN ISO 12100-2:2003", and for safeguarding measures, see !Clause 5 of EN ISO 12100-2:2003". 5.1 Controls 5.1.1 Safety and reliability of control systems For the purposes of this European Standard a safety related control system is one from and including the initial manual control or position detector to the point of input to the final actuator or element e.g. motor. The safety related control systems of this machine are those for:  starting (see 5.1.3);  normal stopping (see 5.1.4);  emergency stop (see 5.1.5);  moveable interlocked guards (see 5.1.3, 5.2.7.3);  moveable interlocked guards with guard locking (see 5.2.7.1, 5.2.7.2, 5.2.7.3);  interlocking of the cutting stroke with saw blade rotation and workpiece clamping (where fitted) (see 5.1.3 and 5.2.7.1.2);  interlocking of the powered workpiece positioning with the cutting stroke (see 5.1.6);  hold-to-run control device (see 5.2.7.1.2);  mode selection (see 5.1.7);  initiation of the braking system (see 5.1.4, 5.1.5, 5.2.4);  two hand control devices (see 5.2.7.1);  pressure sensitive mats (see 5.2.7.1, 5.2.7.2);  active optoelectronic protective devices (light barriers) (see 5.2.7.1, 5.2.7.2);  mechanically actuated trip devices (trip bars) (see 5.2.7.2 );  workpiece clamping (see 5.2.8). Unless otherwise stated in this European Standard these control systems shall, as a minimum, be designed and constructed in accordance with category 1 as defined in !EN ISO 13849-1:2008". For the purposes of this European Standard "well tried components and principles" means: a) electrical components if they comply with relevant standards including the following as: i) !EN 60947-5-1:2004" (section 3) for control switches with positive opening operation used as mechanical actuated position detectors for interlocking guards and for relays used in auxiliary circuits; ii) !EN 60947-4-1:2001" for electromechanical contactors and motor-starters used in main circuits; iii) !HD 22.1 S4:2002" for rubber-insulated cables; SIST EN 1870-10:2004+A1:2009

EN 574:1996; h) pressure sensitive mats if they are as minimum in accordance of type 2 of EN 1760-1:1997 and if they are tested together with their associated control circuits at least at each starting of the machine; i) active optoelectronic protective devices (light beam) if they comply as minimum of type 2 of
!CLC/TS
61496-2:2006" and if they are tested together with the associated control circuits at least at each starting of the machine; j) trip bars if they are as minimum in accordance with type 2 of EN 1760-2:2001 and if they are tested together with their associated control circuits at least at each starting of the machine. Time delay devices used in hardwired safety related control circuits may be of category B in accordance with the requirements of !EN ISO 13849-1:2008" if the time delay device is designed for at least one million actuations. Verification: By checking the relevant drawings and/or circuit diagrams and inspection of the machine. !deleted text" !NOTE For components characteristics the information from the component supplier can be useful." 5.1.2 Position of controls The main electrical controls for starting the saw blade spindle drive motor, normal stopping and integrated feed of the workpiece (where fitted) shall be located together on the machine or on a mobile control desk from which the loading position can be seen (see also !11.2.1 of EN 60204-1:2006").
Where controls are located on a mobile control desk the following requirements shall be met: a) it shall be connected by cable to the machine; b) its position shall be indicated in the instruction handbook. Where the machine is fitted with a two-hand control device it shall be: SIST EN 1870-10:2004+A1:2009

c) at the main control panel; d) within 500 mm of the two-hand control device (where provided); e) within 3,0 m of the saw unit. NOTE A single emergency stop can be positioned to fulfil more than one of these requirements. Verification: By checking the relevant drawings, measurement and inspection of the machine.

This is achieved by the interlocking arrangements described in 5.2.7. Start or restart shall only be possible by actuation of the start control device provided for that purpose. For semi-automatic machines the cutting stroke shall only be capable of being started with a manually operated control device after saw blade rotation and clamping have been initiated. For all machines the cutting stroke shall only be capable of being started when: a) saw blade rotation and workpiece clamping (where fitted) have been initiated; b) all interlocked guards are in the closed position; c) no person is standing on pressure sensitive mats (where provided); d) no person is within the beams of an active optoelectronic device (where provided). All reset controls shall be located outside protected areas and not reachable when standing inside a protected area. For electrically started machines see 9.2.5.2 of !EN 60204-1:2006". The exceptions described with regard to 9.2.4 of !EN 60204-1:2006" are not relevant. Verification: By checking the relevant drawings and/or circuit diagrams, inspection and relevant functional testing of the machine. SIST EN 1870-10:2004+A1:2009

!EN 60204-1:2006". However !10.7.4 of EN 60204-1:2006" does not apply. When actuated the emergency stop shall disconnect power from all machine actuators and actuate the brake (if provided). When initiated the stopping sequence shall: a) initiate the return stroke of the saw unit; b) remove power to workpiece clamping (where fitted); c) cut power to saw spindle motor and initiate the brake (where fitted); d) cut power to brake when braking sequence is complete (if electrical brake is fitted). The stopping sequence shall be satisfied at the level of the control circuits. If a time delay device is used, time delay shall be at least the maximum run-down time and either the time delay shall be fixed, or, the time delay adjustment device shall be sealed. For positioning of the emergency stop control(s) see 5.1.2. Verification: By checking relevant drawings and/or circuit diagrams, inspection and relevant functional testing of the machine. 5.1.6 Integrated feed The integrated feed of the workpiece positioning mechanism shall only operate when the saw unit is in its rest position. For the integrated feed of the saw unit see 5.1.3. SIST EN 1870-10:2004+A1:2009

c) changing the mode shall not initiate any movement of the machine. Verification: By checking relevant drawings and/or circuit diagrams, inspection and relevant functional testing of the machine. 5.1.8 Failure of the power supply On electrically driven machines an automatic restart in the case of a supply interruption after the restoration of the supply voltage shall be prevented in accordance with 7.5 paragraphs 1 and 3 of !EN 60204-1:2006". Where pneumatic or hydraulic workpiece clamping is provided, in the event of loss of pneumatic or hydraulic pressure, clamping of the workpiece shall be maintained until the return stroke of the saw blade is initiated. Where non-return valves are used to meet this requirement, they shall be fitted to the actuating cylinders.
The automatic restart of the machine shall be prevented after restoration of the pneumatic or hydraulic energy. Verification: By checking relevant drawings and/or circuit
